shibby20, big thx for answer!
I run "route" command and see not all routes...(for example: I try to connect to retracker.local and recive connection timeout. when I manualy add route for retracker.local, I connect succesful.)

My ISP is "beeline moscow" and all routes recived successful on builds 110 and early.

without this routes I cant open local sites, resources, and providers statistic/pament page/iptv... etc.

Shibby, I can provide you all logs what you want! I need to fix this serious problem.

FYI the firmware from the official asus support works good with Dual-Access. What's more it has Dual-wan support.
I tested ASUS RT-N16 Firmware version 3.0.0.4.374.5517.
But it has fewer features then Shibbis' one.
